Verify Quality of Grounding Connections and Bonds with the AEMC 6416

AEMC 6416 Clamp On Ground Resistance TesterGood grounding is important to prevent costly damage and downtime due to service interruptions and inoperative surge protection caused by poor grounds.

Grounding systems offer protection from natural occurrences such as lightning by channeling the lightning current to the ground, protecting personnel from injury and protecting system components from damage.

In electric power systems with ground returns, grounds help guarantee rapid operation of the protection relays by providing low resistance fault paths in the event of unexpected potentials due to faults.

Low ground resistance is required to meet NEC® , OSHA and some warranty requirements plus other electrical safety standards.

The AEMC 6416 Clamp-On Ground Resistance Tester measures ground rod and grid resistance and impedance without the use of auxiliary rods. 

Three features unique to AEMC 6416 Clamp-On Ground Resistance Tester are:

  • Test frequency selection provides more accurate results in inductive environments

  • Touch voltage indication indicates the voltage on the display along with a warning buzzer when the voltage derived from current and resistance measurements detect a potentially dangerous touch condition

  • Loop resistance indication alerts the user to the fact that the measurement may not be ground resistance

6416 applications:

  • Ground electrode system resistance
  • Bonding/continuity checks

  • Cell tower grounding verification

  • Ground measurements on Railroad signaling systems

The 6416 includes a high sensitivity measurement function enabling measurement of leakage current flowing to ground or circulating in ground loops from 0.2mA to 40A and resistances from 0.01 to 1500Ω. It also offers battery life information at power-up and Auto Power OFF power management. The Buzzer and Auto Power OFF features may be disabled at any time.
